From the time of Galileo, it has been observed and believed that the Sun has dark patches (now called as sunspots), on its surface and contain a central region with concentrated magnetic field of strength upto 0.3 T. The magnetic field generates a Lorentz force, which contains two components namely: magnetic pressure force and a tension force ([1]}). The ratio of plasma pressure to magnetic pressure is a dimensionless quantity, called plasma beta `\(\beta \) ' ([2]}):
\(\beta =\frac{2\mu _{o}p_{o}}{B^2}\)
